Killzone: Mercenary only £14.99 on PSN for Vita

Sony's Xmas sale now includes Killzone: Mercenary on the Vita. For a nice change, this digital version is £10 cheaper than the best price I can find for the boxed product. It's a steal at this price, as the game proves that the Vita can do shooters and do them well. Earn cash throughout the single player campaign and then spend it on upgrades for the comprehensive multiplayer. More of this sort of thing please, developer types.
